Abstract
It is object of this invention to provide a mobile device including FM transmitter of which antenna has a less danger to be damaged and it is easy to secure a space for housing of the antenna. A mobile music player is comprising a audio player for generating audio signal that is target of transmission, a stereo modulation circuit for performing FM modulation to the audio signal and thereby generating carrier wave signal which can be received by an FM receiver, an FM modulation circuit, and a transmission circuit for transmitting the carrier wave signal via the transmission antenna 40. These audio signal generation circuit, modulation circuit and transmission circuit are formed on a print substrate 200, and a loop-shaped conductor 40A formed along the outer surface of a housing 300 for housing the print substrate 200 is used as a transmission antenna.
